Stealth Gaming in a Gothic Steampunk World

** The Dark Mod wins PC Gamer's 2013 Mod of the Year award! **

“It’s a tremendous achievement – a detailed tribute to the Thief series…. Projects like The Dark Mod are a way for those fans to say “if you won’t make it, we will” – to deftly lift what was good and meaningful about the games that inspired us years ago and run away with it.”
PC Gamer

“this is splendid….it’s basically Thief…but in Doom 3.”
–Rock, Paper, Shotgun

THE DARK MOD was once total conversion of Doom 3, and now is a STANDALONE GAME with the release of TDM 2.0!

A dark and moody stealth game, inspired by the "Thief" series by Looking Glass Studios, The Dark Mod includes creative new gameplay features, dozens of unique AI, and a complete set of custom art assets, allowing players and mappers alike to enjoy missions in a gothic steampunk universe. When you play The Dark Mod, you feel like you’re playing a gothic stealth game…there’s nothing left that’s recognizable from Doom 3.

This game is first and foremost a toolkit, allowing fans and team-members to create their own stealth missions in a gothic steampunk environment. But there are already over 80 full missions for download, including some small campaigns, so it certainly feels like a game. The only difference is that you have to choose which missions to install and play.


The Dark Mod world can be viewed as an alternate version of our own. It is a mixture of several historical periods, with architecture ranging from medieval castles to Victorian mansions. In this world, steam and clockwork technology were discovered much earlier in history, allowing for odd inventions and industrial warehouses to exist side-by-side with Gothic cathedrals and sword-wielding city watch.

We also maintain our own mission editor, called Dark Radiant. It is an updated version of GTKRadiant, and has a lot new features (Python scripting support, many bug-fixes, new Particle preview, Texture Tool etc.) and comes with a number of Dark Mod related plug-ins like an Objectives or Conversation editor.

May Mission Madness!

What if I told you Moonbo was releasing a two mission

campaign follow-up to his acclaimed mission Requiem?

What if I told you that Sotha was also releasing

the hotly anticipated sequel to his new Ulysses series?

What if I told you Bikerdude has just done a

vast overhaul of the No Honor Among Thieves campaign?

Only one of these announcements might bowl you over, now... it's time to faint!

A House of Locked Secrets

Hols splash big

Moonbo has pulled out all stops in this two mission campaign follow-up to his widely praised "Requiem" mission. With peerless architecture, elegant and inventive scripted sequences, top-notch story development, and so much polish that triple AAA studios would hang their heads in shame at the sight of it... "A House of Locked Secrets" is an instant classic and elevates itself to more than just a Dark Mod mission. A must play!


Ulysses 2: Protecting the Flock



Sotha continues to push new mapping frontiers and using his experiments to churn out some of the best and most anticipated missions for The Dark Mod. For Ulysses 2, he extends his modular building techniques and throws in many new custom character animations and assets. With 3 different play styles, and Sotha's typically devilish AI routing there will be plenty of reasons to reply this mission.

No Honor Among Thieves v3



After spending a great deal of time making "No Honor Among Thieves" ready for 2.0 standalone, a few last minute mod bugs spoiled the release so Biker put his nose to the grindstone and set out to release the most flawless edition of this mission ever to grace the mission database. Not content with just fixing reported bugs, Biker optimized areas in new ways, learned more about the LOD system (and had SteveL fix some bugs for it), re-lit scenes, added new textures, improved buildings to make game-play more varied, added new particle effects, and just plain upgraded this mission in every way possible. Crypts are creepier, Pubs are cozier, Inns are sleazier, Cathedrals are more grand, Forests are darker... More than enough reasons to play or replay this 3-mission campaign.

hey snakedog,

We're happy to help you with problems, TDM have a tech support forum on the site and it's recommended to use that. (I'd post a link but newbie accounts cant). Please also use the official forums for any feedback and such as it's much easier to reply to etc and the team reads everything there :)

However make sure you read the wiki/FAQ which covers quite a few problems that are out of our hands. It's likely that you need to drop your interaction shader quality (in the graphics menu) to fix that(Its a problem with geforce 6xxx's iirc). If that fails please make a thread in the support forum and try include a screenshot :)

By the way for those of you looking for a great FM to start with first, I recommend Patently Dangerous. I've tried quite a lot of FMs over the last few days, and while I think their quality is really up to par with many commercial games (and the older Thief games), I highly recommend Patently Dangerous, if only for the fact that it's almost as scary as the Cradle level in Thief: Deadly Shadows.

This positively looks how Thief should feel, if that makes sense. It seems to be truly amazing. Though I always wished the Thief series had a deep melee combat system to go with everything else. Can't wait for undead :).

just looking the video - blackheart manor, I can say that this mod is quite underestimated. It's obvious that there are tons of work in it. The reason why dark mod can't make top 10 is lack of its audience imho. Many gamers prefer first person shooters which I already bored many years ago.

Agreed. I feel there's not enough media coverage on this mod - IMHO this is one of the greatest TCs ever made, all things considered. As was the case with the first two Thief games, this is just as underrated/overlooked by the gaming press.

Great mod, must play for all thief fans. Contains great, userfriendly editor (To tell the truth, this mod is mainly the editor, and fans are making FMsú and a lot of super missions. Try it and you will be surprised.
